The answer is C. decreases.
C-14 and C-12 are carbon isotopes used to measure the approximate age of organic remains. C-12 is stable, and it does not break down into other elements over time. C-14 is not stable. It breaks down into N-14.
Organisms can incorporate C-14 into their bodies during the life. But when the die, C-14 is not incorporated anymore. After organisms' death, C-12 will remain stable, but C-14 will start to breaks down into N-14. So, it will be less C-14 and C-12 will remain the same. The ratio of C-14 to C-12 must decrease over time.

- Similarly poor anger management in childhood leads is associated with low earning during adulthood.
- Hence, Ken's research shows that there is a relationship between <em>childhood</em><em> </em><em>anger</em><em> </em><em>management</em><em> </em><em>and</em><em> </em><em>adult</em><em> </em><em>earnings</em><em>.</em><em> </em>
